Several packages got renamed/updated, libgcrypt was apparently installed by default previously. Since most libraries changed we have to completely rebuild all the tools installed in the root image. We currently don't provide a clean target in the recipes, and even if we did we'd have to track which base image we last built for. It's easier to just use a different build directory for each base image, at the cost of some additional disk space (if not manually cleaned). However, that's also the case when updating kernel or software versions.
